“…В то же время в ПАО «Татнефть» остро стоит проблема повышения нефтеотдачи. Многие нефтяные месторождения разрабатываются с использованием традиционного заводнения [2][3][4][5]. После заводнения в недрах остаются до 70% начальных запасов нефти [6][7][8], которые оказываются сложно рассредоточенными в заводненном объеме пластов в виде остаточной рассеянной нефти.…”

The results of laboratory studies of filtration processes on models of a terrigenous reservoir are presented in order to develop optimal compositions for simultaneous water and gas injection and foam assisted water alternating gas injection on the reservoir. The experiments were carried out on rock samples drilled from the core of terrigenous deposits of the Kynovsko-Pashiy horizon. The use of water-gas mixtures with foam-forming surfactants taking into account the field conditions of the fields of PJSC TATNEFT has been established will make it possible to obtain the greatest increase in oil recovery. Studies of the multiplicity and stability of foam systems have shown that non-ionic foaming surfactants TN-PO-1, TN-PO-2 and AF9-12 are best suited for use in FAWAG of the reservoir. The results of studies of the properties of foams depending on the concentration of surfactants are presented, recommendations are given on the use of specific reagents for the implementation of FAWAG, taking into account the conditions of specific fields. The use of SWAG and FAWAG technologies is not only increase oil recovery, but also significantly reduce the volume of irrationally used associated petroleum gas, which is one of the most important tasks for sustainable development goals. Keywords: enhanced oil recovery; filtration studies; simultaneous water and gas injection; foam assisted water alternating gas injection; foaming surfactants.

“…Известно, что большинство нефтяных месторождений характеризуются многопластовостью [1][2][3][4][5][6][7][8], что требует для повышения степени выработки запасов, проведения надежного контроля и регулирования процесса разработки, выделения пластов и групп в самостоятельные эксплуатационные объекты [9][10][11][12].…”

This article proposes the introduction of SWAG-technology at the Rechitskoe oil field of RUE Belorusneft. An analysis of previously conducted research on the implementation of technology at the selected facility revealed a number of technological factors that reduced the effectiveness of the method. It is proposed to use pump-ejector systems –devices that will allow obtaining and pumping a water-gas mixture with the required pressure. To ensure rational gas content, it is advisable to add flare and flue gases to the water, which will reduce the carbon footprint. The addition of foaming surfactants helps to improve the characteristics developed by the booster pump, suppress the coalescence of gas bubbles and increase the efficiency of injection of the water-gas mixture.
